That way we could at > least start landing the core&driver bits ... I went ahead and sent a PR without the uapi bits.. IMHO I don't think that any further discussion on the MR would change the uapi, but I guess it doesn't hurt giving it some extra days while unblocking the driver parts. I still kinda hope that we can land at least the syncobj UAPI this cycle.
